Renowned ‘Standard Methods’ water manual updated, 22nd edition now available

Washington, D.C. -- The most widely respected and globally utilized water examination manual, Standard Methods for the Examination of Water and Wastewater, has been expanded and revised and is now available in its 22nd Edition.

Published jointly by the American Public Health Association (APHA), the American Water Works Association (AWWA) and the Water Environment Federation (WEF), Standard Methods reflects the latest developments in water analysis. One significant change in this edition is an emphasis on quality assurance/quality control (QA/QC) practices. Both EPA and the Standard Methods Committee feel strongly that QA/QC is necessary to ensure that each method produces accurate results. In total, more than 40 percent of the book is new or updated.

“Along with the American Water Works Association and the Water Environment Federation, APHA is proud to put forth the updated 22nd Edition of this widely used and valued manual,” said Georges C. Benjamin, MD, FACP, FACEP (E), executive director of the American Public Health Association. “In an effort to remain current with the latest science and best practices, the latest edition of the Standard Methods provides greater guidance on quality control steps for those in the field.”

”Standard Methods has for many decades been the trusted source for water professionals,” said AWWA Executive Director David LaFrance. “The latest edition incorporates the best available science to help water professionals achieve all their water analysis and treatment objectives.”

“The 22nd Edition provides more than 400 proven analytical methods — many officially approved by EPA,” said WEF Executive Director Jeff Eger. “This manual belongs on the shelf of any chemist, radiochemist, or microbiologist who evaluates water quality.”

Since the first edition in 1905, Standard Methods has represented the best current practice of American water analysts, covering all aspects of water and wastewater analysis techniques. In 1899, APHA appointed a Standard Methods of Water Analysis committee that was charged with extending standard procedures to all methods involved in the analysis of water. The committee’s report constituted the first edition of the book.
